There's a lot of cases where we try to re-run the same code with different parameters. We currently need to either use a generator method or create a "main" case implementation which then gets called by trivial case functions:
def _test(x, y, z): ...
def case_int(): _test(1, 2, 3)
def case_str(): _test('a', 'b', 'c')
Add support for variants, similar to kselftests_harness.h and a lot of other frameworks. Variants can be added as decorator to test functions:
@ksft_variants([(1, 2, 3), ('a', 'b', 'c')]) def case(x, y, z): ...
ksft_run() will auto-generate case names: case.1_2_3 case.a_b_c
Because the names may not always be pretty (and to avoid forcing classes to implement case-friendly __str__()) add a wrapper class KsftNamedVariant which lets the user specify the name for the variant.
Note that ksft_run's args are still supported. ksft_run splices args and variant params together.
